Description
Technical field
The present invention relates to fabric sofetening composition.Specifically, the present invention relates to visually reach the fabric sofetening composition that attracts the human consumer on the rheological and show good stability.
Background and prior art
It is well-known softening processed fabric with liquid fabric softening composition.This composition adds in the fabric at the rinse stage of washing process usually.Have been noted that the consumer preference thickness and be butyraceous liquid fabric conditioner, this means that this class amendment has high viscosity and high opaqueness.Can think the amendment low grade and the poor efficiency of thin and/or translucent/water sample, on the contrary thickness and to be butyraceous amendment be expensive goods.A kind of approach of this effect that realizes is to use polymeric viscosity modifiers.
The fabric conditioner that comprises polymeric viscosity modifiers and cationic softener is well known in the art.For example, WO-A1-02/081611 discloses the fabric softener composition of handling textile fiber material in the household application, and described composition comprises fabric softener and can be by glycol that makes (a) vulcabond and the polyethers that (b) contains at least one hydroxyl, aliphatic residue that (c) optional deriving from have 2-12 carbon atom and the aqurous ployurethane of (d) introducing the reagent react acquisition of water soluble group.
US 2004/0214736, US 6827795, EP 0501714, US 2003/0104964 and US 5880084 disclose the fabric sofetening composition that comprises Polyquaternium 24, and Polyquaternium 24 is the epoxide reactive polymkeric substance quaternary ammonium salt of Natvosol and lauryl dimethyl ammonium.
EP-A2-0385749 discloses the fabric-conditioning compositions that comprises soft material of quaternary ammonium and polymer viscosifier.This thickening material possess hydrophilic property main chain and two connected hydrophobic groups.
EP 331237 discloses the aqueous fabric care composition that comprises fabric softener and nonionic cellulose ether, it is characterized in that described nonionic cellulose ether has enough nonionic substitution values that is selected from methyl, hydroxyethyl and hydroxypropyl so that it has water-soluble and wherein said nonionic cellulose ether by further to have about 10-24 carbon atom, amount be that the alkyl of 0.2% weight replaces and changes hydrophobicity by one or more, this amount makes the ether of cellulose that is lower than 1% weight under 20 ℃ be dissolvable in water in the water.The Natvosol (HMHEC) that preferred nonionic cellulose ether changes for the hydrophobicity of buying from Hercules Incorporated with trade name " Natrosol Plus ".The specific examples of disclosed HMHEC has Natrosol Plus 330 and Natrosol Plus 331 in fabric-conditioning compositions.The HMHEC polymkeric substance realizes that by form key between the dispersed particle of fabric conditioner system viscosity increases, and promptly it serves as " associative thickener ".This with simply form contrast without any associating " external phase thickening material " by the continuous phase transistion thickness is worked.The benefit of HMHEC is that it has more the validity of unit weight, therefore is the solution that has more economic benefit, thereby realizes the product high viscosity and reduce materials consumption simultaneously, and is promptly more friendly to environment usually.
If this base polymer before used with rare product, prove usually that then this base polymer is the most effective with the softening agent actives that mainly contains the dialkyl cationic material under proper temperature (＜37 ℃).Under comparatively high temps, composition since the hydrolysis gelling before viscosity certainly will significantly reduce.If target viscosities is than higher, then this is unfavorable especially.
In order to keep product viscosity, HMHEC must keep associating or " combination " with disperse phase.If polymkeric substance loses this combination, then the hydrophobic part of polymkeric substance may intramolecularly associates, and to make that viscosity is reduced to specification standards following and product is thinning and be easier to separate.Another key issue about TEAQ type actives is that this class actives may contain a large amount of monoesters components more soluble in water.This component becomes along with system temperature raises even is more soluble in water, thinks that this can cause forming the micelle type structure in external phase.Think that this micella promotes the hydrophobic chain of polymkeric substance to discharge from the bilayer that disperses organic phase.In addition,, have more hydrophobic three esters and diester material decomposition and form the monoesters product, therefore further aggravated this problem along with actives hydrolysis under this hot conditions of ester linkage.
Be conceived to above point and produced the present invention.
Summary of the invention
